PLOW-COLTER.

Specification of Letters Patent.

Patented J an. 29, 1918.

Application filed January 5, 1917. Serial N 0. 140,817.

To all wkom it may concern:

Be it known that I, JOSEPH A. CLoUA'rnn, a citizen of the United States, residing at Brittany, in the parish of Ascension and State of Louisiana, have invented new and useful Improvements in Plow Colters, of which the following is a specification.

This invention relates to plow colters, and it has for its object to produce a simple and improved device of this class which may be readily applied and used in connection with almost any conventional plow, and especially the plows having a metallic beam and standard.

A further object of the invention is to produce a plow colter which will be particularly adapted for use in grassy land or in land that is infested with loads of weeds and plants, without danger of becoming choked so as to obstruct the progress of the plow.

A further object of the invention is to pro duce a colter blade of simple and improved construction which may be readily applied and used.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and par ticularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the .recise structural details therein exhibited, 'ut that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawing,

Figure 1 is a side elevation of a plow to whiclh the improved cultivator has been apliec P Fig. 2 is a side view enlarged of the colter blade detached.

Fig. 3 is a sectional view taken on the line 3-3 in Fig. 2.

Fig. 4 is a sectional detail view taken on the line 44 of Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved colter blade B is made of a Hat piece of steel, said blade being arcuate or simitar shaped and having at one end what may be termed a handle portion 15 which is straight. One side face of the blade B, which lies in the plane of the land side of the plow when the device is mounted in position for use, is perfectly flat and smooth; the opposite side, which faces the furrow side of the plow is drawn out as best seen at 16 in Fig. 3 to produce a sharp cutting edge 17 at the convex edge'of the blade. The concave edge portion which forms the back of the blade retains the full thickness of the blade. The back portion ofthe blade, at the point of the latter, is cut off obliquely in an upward and rearward direction, as seen at 18, the extreme point being rounded, as seen at 20, and the cutting edge formed by the beveled or drawn out portion 16 being continued around the rounded end portion of the blade so as to terminate in the rearwardly disposed oblique portion 18, as clearly seen in Fig. 2.

The blade may be mounted on the stand-=.

ard C by means of a clamp 19 engaging the straight handle portion 15 of the blade and the standard on which the blade will thus be clamped securely. The blade is to be mounted in such a position that the point thereof indicated at 20 will lie slightly above and in advance of the plow point 21. Thus, when the plow and the colter enter the ground, the arcuate convex edge of the blade will cut in advance of the plow, severing grass, roots and the like with a shearing cut, thereby greatly facilitating the progress of the plow. The arcuate cutting edge will continue to be effective the full length thereof, which materially exceeds the length of any colter that could be attached to the beam of the plow. There will be no opportunity for roots, weeds or the like to become choked or wedged between the plow point, and the colter, the cutting edge of the latter being continued around the point 20 so that any material entering between said point and the plow point will be severed, and the purposes of the invention will, therefore, at no time be interfered with.

The improved colter blade is extremely simple and inexpensive and it has been found by practical tests to be thoroughly useful and serviceable for the purposes for which it is provided.

Having thus described the invention, what and extending forwardly below the beam, 7

said blade having its terminal portion cutin oil obliquely in an upward and rearward direction and rounded at the extreme end thereof, said blade having a cutting edge extending around the rounded end portion.

and merging in the obliquely cut-off portion. 15 In testimony whereof I affix my signature JOSEPH A. CLOUATRE.
